The outgoing energy flux of massless scalar particles created by the gravitational field of a bubble of anti-de Sitter space expanding into Minkowski space is calculated. The flux is proportional to the curvature coupling constant (ξ) of the scalar field. A positive flux, such as for a conformally invariant scalar field (ξ=1/6), would help stabilize Minkowski space against decay.
I would like to thank B. Allen for helpful discussions.
